• Select a course that interests you – perhaps based on subjects you’ve enjoyed in the past or a new subject you’re excited to try for the first time! If you’re not sure where to start, you can review our Registration Instructions for tips on browsing by topic or Hub requirement.

CAS Language Course: CAS students must exhibit proficiency through the fourth-semester level of a language other than English. If you have not already done so, please review the full language policy here.

If you will fulfill this requirement through coursework at BU, then your next course should be a language course. If you’re new to the language, you’ll start with the first-semester level (usually coded as 111 – for example, Spanish 1 is LS 111, Arabic 1 is LY 111, etc.). If you have previously studied the language, you will need to take a placement test to determine what level to start with (for instance, LS 112 Spanish 2, LY 211 Arabic 3, LK 212 Korean 4, etc.). Please review the CAS Language Requirement page for detailed information about placement tests and appropriate levels.

If you are fulfilling your language requirement through advanced credit (such as AP/IB scores) or through native proficiency of another language, please read below for other options.
